Is this an example of what backlash can do?

ok..... so I've just found a setting for axis calibration and adjusted as follows.....:

X set to move 80mm and moved only 77mm
y set to move 80mm and moved 80.5mm
z set to move -50mm and moved -48.5mm

lets see if this make a significant difference.

Also noticed this line in the GCode:

N80X0.000Y0.000F2400.0

Is the F for feed rate and is it too fast...?

Thanks in advance!!!
